Problems solved by technology

Due to the long-term use of these agents, they have produced different degrees of drug resistance, and the control effect is reduced.
At the same time, the extensive use of medicaments increases pesticide residues, endangers food safety, and aggravates environmental pollution.

[0026] Bioassay Example 1: Indoor Toxicity Determination of Flumorph and Fluazinam or Fluoxamid or Cymoxanil on P. infestans P. infestans

[0027] Test object: Potato infestation fungus (Phytophthora infestans) collected from the field

[0028] Test method: refer to the mycelium growth rate method in "Agricultural Industry Standard NY / T1156.2-2006 of the People's Republic of China". Cultivate P. infestans infestans with PDA medium. When the colonies just cover the petri dish, use a puncher with an inner diameter of 7 mm to punch holes from the edge, and the punched mycelium blocks are used as inoculum. Take 5 mL of the prepared drug solution and mix them with quantitative 75 mL of sterilized medium to make 4 drug-containing plates, and use the same amount of sterile water mixed with the medium as a control. The mycelium block was placed upside down and placed in the center of the plate, and then placed in a 28°C incubator for cultivation. After 7 days, the diameter of the co...

Abstract

The invention relates to a flumorph-containing sterilizing composition. The active ingredients of the sterilizing composition comprise flumorph (A) and one (B) of fluazinam, fluopicolide and cymoxanil, wherein the mass ratio of the A to the B is 100:1 to 1:100, and the active ingredients accounts for 15 to 80 percent of the mass of the composition. The composition can be prepared into any agriculturally acceptable formulation, and preferred formulations comprise suspending agent, wettable powder, and water dispersing particles. The sterilizing composition of the invention is applied in fields of farmlands, orchards and like and used for preventing and controlling various plant diseases, particularly powdery mildew and epidemic diseases, on crop such as corn, vegetables, fruit trees, flowers and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing flumorph and fluazinam or fluopyram or cymoxanil, belonging to the field of agricultural fungicides. Background technique [0002] Downy mildew is one of the most important diseases in vegetable production. Downy mildew can occur at all stages from seedlings to harvest, and the adult plants suffer the most. It mainly damages the leaves and develops from the base to the upper leaves. In the early stage of the disease, light yellow sub-circular to polygonal lesions are formed on the leaves. When the air is humid, a frosty mold layer is formed on the back of the leaves, and sometimes it can spread to the leaves. In the later stage, the disease spots are withered and contiguous, and they are yellowish brown. In severe cases, all the outer leaves are withered and yellow and die. Field planting is too dense, watering too early after planting, too la...
